The last exception that was thrown in the REPL; null if nothing has
yet been thrown.

The last exception that was thrown in the REPL; null if nothing has
yet been thrown. Useful if you want additional information from the
thrown exception than the printed stack trace (e.g. many exceptions have
additional metadata attached) or if you want to show the stack trace
on an exception that doesn't normally print it (e.g. seeing the stack
when a Ctrl-C interrupt happened) via lastException.printStackTrace.

Functions that can be used to manipulate the current REPL session:
check-pointing progress, reverting to earlier checkpoints, or deleting
checkpoints by name.

Frames get pushed on a stack; by default, a saved frame is
accessible simply by calling load. If you provide a name
when saveing a checkpoint, it can later be loaded directly
by providing the same name to load

Un-named checkpoints are garbage collected, together with their
classloader and associated data, when they are no longer accessible
due to restore. Named checkpoints are kept forever; call delete
on them if you really want them to go away.
